Perhaps, but check that it had the m57 and not the n57 in the f15 x5. Pretty sure it was the latter.

As an aside, I convinced my Dad to buy a 535d to replace his 328d that was sent to an early grave by a young driver. He loves it. And the gas mileage is crazy. 40+mpg when we drove it home from Kentucky. Glad he went for it, he's to old and too big to be driving a small 3 series.
